Summary :

ANTCLABS Genuine BL Touch V3.1   is an auto leveling sensor for 3D Printers that can precisely measure the tilt of Bed surface. It could work with any kinds of bed materials, such as glasses, woods, metals, and so on.

Blue & Red LED : Blue and Red LED for checking wiring defects.

Main functions and controls of BLTouch are the same as usual auto bed leveling sensor, consists of RC servo and micro switch. Thus, BLTouch can be applied on almost every board.

BLTouch is fulfilled with simple structure and high precision by using progressively designed solenoid and hall sensor. It aims for user convenience and enjoyable printing by adding many smart functions, such as self-test, alarm, alarm release & Touch Switch mode, Blue LED for servo signal indicating and Z-probe(Zmin) Testing.

Hall Sensor : Free Bed Selection

BLTouch does not uses either optical, nor proximity(inductive/capacitive) sensor.

BLTouch is controlled by hall effect, providing high precision. Thus the bed material can be selected freely.
